today i cleaned out the water inlets to our washing machine, after i was made aware that it doesn't fill from hot or cold.
we have well water, and lots of silt/sand/tiny rocks/rust get pushed through the pipes and land on the screens of the inlet.

i use a lab 'wash bottle' to jet the silt out of there onto an old towel.

i end up doing this every couple of months. this, plus the annual mixing-cartridge replacement for the kitchen sink, means i should probably invest in a whole-house filter.
